Modifies the try-catch for imports of required dependencies (
numpy
,pytz
, anddateutil
) to record any exceptions raised, and then to include the message from these when reporting that required dependencies are missing.Previously, the error message simply claimed the dependency was missing, which was somewhat misleading if the dependency was installed but raised its own ImportError (missing sub-dependencies, bad install, etc.).
